FIRS Extends Deadline for Large Taxpayers on E-Invoicing & E-Fiscal System (EFS)

The Federal Inland Revenue Service (FIRS) has announced a three-month extension for the mandatory onboarding and transmission of electronic invoices under the National E-Invoicing & Electronic Fiscal System (EFS) regime. This extension applies to Large Taxpayers (businesses with annual turnover of ₦5 billion and above) who are required to comply with the new Merchant-Buyer Solution (MBS) platform. While the E-Invoicing & EFS system officially went live on 1 August 2025, the deadline for full onboarding, integration, and mandatory compliance has now been shifted from 1 August 2025 to 1 November 2025. According to the FIRS, this adjustment recognizes the operational challenges faced by many taxpayers in meeting the initial timeline, despite the successful go-live of the platform.

What is the E-Invoicing & EFS System?

The National E-Invoicing & Electronic Fiscal System (EFS) is a digital solution introduced by FIRS to modernize and streamline Nigeria’s tax compliance framework. Through the Merchant-Buyer Solution (MBS) platform, businesses will:

Issue invoices electronically in real-time.
Ensure transparency in transactions between buyers and sellers.
Enable automatic transmission of invoice data directly to FIRS.
Reduce risks of tax evasion, manipulation, or under-reporting.

The system will also provide FIRS with more accurate transaction data, strengthening Nigeria’s tax administration and fostering a fairer business environment.

Why the Extension Matters

The extension offers taxpayers additional time to finalise their onboarding, integration, and compliance procedures. More importantly, it reflects FIRS’ commitment to encouraging voluntary compliance rather than penalizing businesses struggling with technical or operational bottlenecks. In its statement, the agency emphasized that the move is intended to create a smoother and more inclusive transition into the e-invoicing regime, allowing businesses to adapt without disruption to their operations.

FIRS’s Commitment to Support

FIRS has pledged to continue working closely with stakeholders through engagements, technical support, and ongoing training programs. Businesses are encouraged to take advantage of this window to complete the necessary integrations and avoid last-minute compliance challenges. FIRS Executive Chairman, Zacch Adedeji, Ph.D., reaffirmed that the introduction of the e-invoicing platform is part of FIRS’ broader reforms aimed at modernizing Nigeria’s tax system, improving efficiency, and ensuring fairness in tax administration.
